A re­cent in­ter­na­tional study has proved that yearly pneu­mo­coc­cal and in­fluenza vac­cines can check the ag­gra­va­tion of chronic ob­struc­tive pul­monary dis­ease (COPD).

On World COPD Day on Novem­ber 15, Dr Naren­dra Khip­pal, pro­fes­sor, in­sti­tute of res­pi­ra­tory dis­eases, Sawai Man Singh (SMS) Med­i­cal Col­lege Jaipur, said, acute ex­ac­er­ba­tion is the main cause of 50% deaths in COPD. A pneu­mo­coc­cal vac­cine once a year and in­fluenza vac­cine twice a year can check most of these deaths.

Ac­cord­ing to Khip­pal, these vac­cines were avail­able in In­dia over the last few years but since there wasn’t any con­crete study, they were used very less among COPD pa­tients. “Now with proven re­sults of vac­cines, more and more COPD pa­tients will be ben­e­fit­ted,” he said.

Cen­tre for Dis­ease Con­trol and Preven­tion (CDC), USA, in a re­cently pub­lished re­port stated that in­fluenza and pneu­mo­coc­cal vac­cine low­ers the risk of COPD ag­gra­va­tion. This study had started in 2012 was car­ried out on 146 pa­tients.The re­port was pub­lished in the yearly ID Week Jour­nal 2017.

The num­ber of acute ex­ac­er­ba­tions, hos­pi­tal­i­sa­tions, ICU ad­mis­sions, in­va­sive me­chan­i­cal ven­ti­la­tion and mor­tal­ity were an­a­lysed on 146 COPD pa­tients for one year with pneu­mo­coc­cal polysac­cha­ride vac­cine and the out­come was com­pared with 146 un­vac­ci­nated con­trol-group pa­tients.

The ex­per­i­ment showed that there was a sig­nif­i­cant re­duc­tion of hos­pi­tal­i­sa­tion and ICU ad­mis­sions for the vac­ci­nated group.
